tomcat - CXF 类未找到 neethi/PolicyComponent 异常

Question

有人可以解释这个错误的原因吗？我仅在部署应用程序(在 Tomcat 服务器中)时收到此错误。在我的开发机器和其他机器上，这工作正常。我们在 Jetty 上运行应用程序，即使我在本地计算机上的 Tomcat 中运行，它也能正常工作。是不是访问权限问题？当我手动添加 neethi.jar 文件时，抛出 NullPointerException。有什么想法吗？我正在使用 CXF 2.3.3

Answer 1

好的。这与 Maven 有关。当 Maven 构建最终的 war 文件时，它没有包含 CXF jar 依赖项。这导致了问题。
